- What It Is
Engineered for Precise Refrigerant Charging
Patvin offers a reliable and high-performance AC Gas Charging Machine designed for the precise, efficient and rapid charging of refrigerant gas in automotive AC systems, suitable for use in all vehicle types. Its advanced features, user-friendly interface, & focus on safety, significantly enhance production processes & improve the overall quality of vehicles.
R134a
Standard refrigerant for older & conventional vehicles
R1234yf
Eco-friendly refrigerant for modern new-generation vehicles
- Each machine is dedicated to one refrigerant type — mixing is not supported.
- Core Functions
Two Stages. Complete Automation.
Every charge cycle executes a complete, automatic process — no manual intervention required at any stage.
Leak Test
Nitrogen pressure testing ensures absolute zero leakage of refrigerant gas before the charging cycle begins — no waste, no hazard, no risk.
Vacuum Evacuation
Achieves a powerful 1 mbar vacuum at the gun tip, removing all moisture and air from the AC system before gas injection for clean, contamination-free filling.
Refrigerant Charging
Fills the system with a precisely calibrated amount of R134a or R1234yf refrigerant, with optional PAG compressor oil injection — measured to ±20g accuracy.
Detailed Reporting
Automatically generates and prints detailed reports on each charging cycle for quality control records and operational data analysis — full traceability at every stage.
- All four stages execute automatically with a single button press. Barcode scanning adjusts parameters automatically per vehicle model — no manual configuration needed.

Built for the Shop Floor
Customized Design
Each machine is tailored to fit seamlessly into your existing production workspace — custom dimensions, mounting options, and interface layouts available on request.
Smart Barcode Selection
Barcode scanning automatically adjusts all charging parameters — gas volume, pressure, and oil quantity — per vehicle model. No manual entry, no human error.
Proactive Maintenance
The machine continuously monitors its own components to identify potential issues before they escalate, preventing unexpected downtime and production delays.
Efficient Troubleshooting
Built-in fault diagnosis provides clear error codes and resolution guidance, minimizing downtime. Operators can resolve most issues without external service.
Energy Efficient
Intelligent machine operation optimizes energy consumption throughout each charging cycle, reducing operational costs without compromising on speed or accuracy.
Real-time Monitoring
Live dashboard shows gas pressure, vacuum level, oil volume, and cycle status at every moment — ensuring full quality control and production transparency.
Quick Gun Replacement
The charging gun is designed for rapid, tool-free replacement. Operators swap the gun in seconds — minimizing line stoppage during maintenance.
High-Quality Components
Every internal component is sourced from reputable manufacturers, ensuring long service life, consistent performance, and full warranty coverage.
